The Holy Crown of Hungary, (side view) presumed made in Constantinople in the 1070s, was the coronation crown used by the Kingdom of Hungary for most of its existence; kings have been crowned with it since the twelfth century.

In the history of Hungary, more than fifty kings were crowned with it, up to the last, Charles IV, in 1916.
